Just finished building the power supply for my second G7 mic. After chasing down a problem with a stray solder bridge, all is well. Except.....
On my first power supply, I read the following voltages (these are all WITHOUT the mic connected):
Pin 2 = 172VDC
Pin 5-Figure 8 = 172VDC
Pin 5-Omni = 0VDC
Pin 5-Cardioid = 83VDC
Pin 6 = 6.3VDC
On the second power supply, I read the following:
Pin 2 = 236VDC
Pin 5-Figure 8 = 236VDC
Pin 5-Omni = 0VDC
Pin 5-Cardioid = 114VDC
Pin 6 = 6.2VDC
All components between the two are identical except for the second transformer, the one wired "backwards."
On the first supply, that transformer is an Amveco 62013 3.2VA. On the second supply, it's an Amveco 62042 10VA. (I got it cheap from a surplus supply company.)
Is that the short answer for the discrepancy? Is there any harm/advantage to keeping it?
